APPARATUS FOR MOISTENING STAMPS, 84.0.

SPECIFICATION forming part of Letters Patent No. 335,580, dated February9, 1886.

Application filed September 23, 1884. Serial No. 143,783. (No model.)Patented in Germany May 3, 1884, No. 28,467, and in England, May 30,1884, No. 8,452.

To all whom. it may concern:

Be it known that I, BERNHARD GRiiNnLER, a subject of the King ofPrussia, Germany, residing at the village of Petersdorf, near Zielenzig,in the Kingdom of Prussia, have invented new and useful Improvements inApparatus for Moistening Stamps, Labels, and Similar Articles, of whichthe following is a specification.

This invention relates to a moistening apparatus for stamps, labels, andsimilar articles.

In describing the invention reference is made to the accompanyingdrawings, Figures I to VIII, which represent various modifications anddetails of apparatus embodying this invention. Two liquid-receptacles, Aand B, are placed side by side at different levels and provided withbase-plates F and G, forming an angle which is less than one hundred andBetween the two receptacles is situated the moistening-surface O, andeach receptacle has a slit, 8, for the discharge of the water. The upperreceptacle, A, is filled with water, which is slowly discharged throughthe slit 8, passes over the surface between the two slits, and entersthrough the lower slit into the receptacle B. After the receptacle A hasbeen gradually emptied, whereby the receptacle B has been filled, theapparatus is reversed, so that B is placed above and A below, whereuponthe action of the apparatus is renewed. For the purpose of obtaining therequired effect, the air'spaces of the receptacles A and B are eitherconnected with each other by a connecting-pipe, M, or the receptaclesare provided with apertures 0 0, through which the air passes in andout. The moistening of the moistening-surface G is caused by the law ofgravitation of the liquid, assisted by the capillary attraction of themoistening-cloth f, which is immersed in the liquid of one or bothreceptacles.

Figs. I and II represent a vertical section and front view of such anapparatus. A and B are the two receptacles; F and G, the baseplates; 0,the moistening-surface; f, the moistening-strip, made of felt, cloth, orblottingpaper, or any other suitable material. 1" r show theconnecting-pipe of the two air-spaces,

which may be replaced by apertures 0 0 with stoppers t t. (Representedin dotted lines.)

Fig. III represents the above-described apparatus in the reversedposition, and shows in dotted lines that the moisteningsurface may alsobe angular.

Fig. III represents the moistening-surface arranged at a level with theside walls of the receptacles A and B.

Fig. IV represents a modified arrangement of the felt strip f, owing towhich the walls of the receptacles A and B themselves serve as amoistening-surface, so that the central moistening-surface, C, mayeventually be entirely omitted. 00 is a flange of the apparatus,protruding sidewise. 0 0 and s s are apertures in the receptacles, theapertures s 8 being preferably small holes, while the apertures 0 0' arebroad slits, so that the water discharged under pressure at s, whichdoes not enter at 8, passes through the broad slit 0 into the receptacleB. In some cases it is sufficient if the effect of the capillaryattraction of the moistening cloth f only is used for moistening thesame. (See Figs. V and VI.) If, in the apparatus represented in Fig. IV,the small apertures s and s are omitted, the removal of the water fromthe receptacle A to the receptacle B is effected only by the capillaryattraction of the moistening-cloth f, which is sufficient for all suchcases in which an uninterrupted use of the apparatus is not required.

Fig. VII represents another modificatiomin which the two base-plates Fand G form a cradle by means of the bend k.

Fig. VIII represents a modification in which capillary attraction onlyis used for moistening the surface f.

If, in the construction represented by Figs. V and VII, the wallsseparating the receptacles A and B are omitted, the apparatus isconverted into one receptacle, A, Fig. VIII, provided with two slits, 0and 0, in which an rangement the moisteningcloth f, which passes throughthese slits and is immersed in the liquid, causes the same effect as theapparatus represented above, only somewhat weaker.

What I claim is, in moistening apparatus consisting chiefly of tworeceptacles acting at ternately as feed vessels or receptacles for theceptacles, A and B, a sheet, f, and a pipe, 0,
